G4-68/Y4-68 boiler ventilation fan/boiler induced draft fan

G4-68 and Y4-68 centrifugal fans and induced draft fans are suitable for ventilation and induced draft matching of steam boilers below 230t/h in thermal power plants.

Unless otherwise specified, G4-68 type can also be used for mine ventilation and general ventilation. The medium conveyed by the ventilation fan is air, and the maximum temperature shall not exceed 80 ℃; The medium conveyed by the induced draft fan is flue gas, and the highest temperature shall not exceed 250 ℃. Before the induced draft fan, a dust removal device with a dust removal efficiency of not less than 85% must be installed to reduce the dust content of the flue gas entering the fan and improve its service life.
